Design:
The Laboy pressure-equalizing dropping funnel is designed with an additional narrow-bore glass tube from the upper part of the funnel bulb to the ground glass joint around the stem at the bottom. It also features standard taper glass outer joints at the top and inner joints at the bottom, along with two glass stopcocks.
Usage: This pressure-equalizing dropping funnel is commonly used in organic chemistry laboratories for slowly adding reagents or solvents to a reaction mixture, while maintaining a constant pressure in the reaction vessel. The additional narrow-bore tube allows for pressure equalization between the funnel and the reaction vessel, which prevents unwanted mixing or bubbling.
Material: Laboy glass flasks are heavy-wall designed and made of high-quality borosilicate glass, ensuring uniform wall thickness. The glass is annealed at 800 degrees Celsius, making it capable of withstanding typical laboratory thermal variations in chemistry processes like heating and cooling.
Craft: The Laboy pressure-equalizing dropping funnel is handmade by blowing, ensuring uniform wall thickness and accuracy in the design. The high-quality borosilicate glass used is highly resistant to chemical reactions, ensuring the longevity of the funnel.
Guarantee: Laboy offers a 100% 40-day money-back guarantee on their pressure-equalizing dropping funnel. If the customer is not satisfied with the product, they can return it for a full refund with no questions asked.
